Electric Vehicle Charging Detection and Early Warning System Based on Internet of Thing

Aiming at the frequent fire accidents caused by electric vehicle charging, a detection and early warning system for illegal charging of electric vehicles based on the Internet of Things is designed. In terms of hardware, the main controller adopt STM8S single-chip microcomputer and wireless data transceiver application. Be the 433 radio frequency module. The software adopts the improved ALOHA algorithm, which effectively solves the problem of electronic tag conflicts when there are too many electronic tags for electric vehicles. Experiments show that the design has successfully realized the monitoring and early warning of electric vehicle charging on campus. It can not only monitor the charging status and temperature of electric vehicles in real time, but also send out sound and light warning when the temperature of the electric vehicle exceeds a safe value to avoid fire occurs.
